Nanoparticles are proposed as alternatives to traditional antimicrobial agents. By manipulating a nanoparticle’s core and surface coating, effects against various microbial populations can be customized, known the “designer effect”. However, properties of nanoparticle core–coating combinations understudied; little research exists on their diverse bacteria. The surface-stabilized zero-valent iron nanoparticles (FeNPs) particularly interesting due stability in water ferromagnetic properties. This study explores impact FeNPs coated with three coatings six bacterial species. were synthesized capped L-ascorbic acid (AA), cetyltrimethylammonium bromide (CTAB), or polyvinylpyrrolidone (PVP) using bottom-up approach. Zone inhibition (ZOI) values, assessed through disc diffusion assay, indicated that AA-FeNPs CTAB-FeNPs displayed most potent antibacterial activity.

Recently, the activation of chlorine dioxide (ClO2) by metal(oxide) for soil remediation has gained notable attention. However, related mechanisms are still not clear. Herein, variation iron species and ClO2, generated reactive oxygen species, toxicity degradation intermediates were explored evaluated with nanoscale zero-valent (nFe0) being employed to activate ClO2 polycyclic aromatic hydrocarbon (PAH) removal. With an optimized ClO2/nFe0 molar ratio 15:1 a soil/water 3:1, efficiency phenanthrene improved 12% in comparison that ClO2-alone system. The presence nFe0 significantly promoted consumption (improved 85.4%) but restrained ClO2- generation (reduced 22.5%). surface Fe(II) soluble system was 2.0-fold 2.8-fold after 2 min. Electron paramagnetic resonance analysis, along quenching experiments, revealed Fe(IV), HOCl, •OH dominated system, oxidation contributions, respectively, 34.3%, 52.8% 12.9%. PAHs had lower estimated than those lettuces grown ClO2/nFe0-treated displayed better results bioassay indexes ClO2-treated soil. This study offers new perspectives organic-pollutant-contaminated using metal-activated technology.

Commercial stable zerovalent iron nanoparticles (nZVI) (NSTAR, not activated) combined with ultrasound (US) were tested for Cr(VI) reductive removal (0.3 mM, pH 3, Fe/Cr molar ratio of 3:1) in the presence carboxylic acids (CAs) ethylenediaminetetraacetic acid (EDTA, 1 mM) or citric (Cit, 2 mM), a system open to air. No decay up 180 min was observed under US when only NSTAR used, while other previously commercial nZVI (N25) showed about 40% few minutes but without further removal. The addition EDTA and Cit enabled absence prior activation particles. A pseudo zero-order kinetics followed, yielding 32 49% Cit, respectively. When applied, these values almost doubled, reaching 59 88% mechanism proposed. present results indicate that simultaneous use CAs allows synergistic by avoiding need an step nanoparticles, more effective result compared EDTA.

This study compared the effectiveness of bare zero-valent iron nanoparticles (B-nZVI) and starch-stabilized (S-nZVI) in immobilizing Pb Cd from lead-acid battery waste soils. Both B-nZVI S-nZVI were prepared almost identical manner using technique reducing ferric chloride with sodium borohydride. X-ray diffraction (XRD) dynamic light scattering (DLS) analyses confirmed that polydisperse synthesized. XRD DLS showed had different surface properties. To assess immobilization capability S-nZVI, a composite soil sample was collected an automobile dumpsite. The pH 3.85 levels 16,674 mg/kg 41 mg/kg, respectively. Single extraction procedures 0.01M CaCl 2 , 0.1 M HCl, 0.05 EDTA used to simulate phytoavailable studied. Batch analysis mobile control but immobile treated however not either or mobility decreased increasing doses 0.003 g needed make completely soil. also 1.8-2.49 times more efficient than B-nZVI. Simulated phytoavailability order > HCl H O while simulated photoavailable .
